Title:
HEAT EXCHANGE TUBE, HEAT EXCHANGER AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/114325
Kind Code:
A1
Abstract:
A heat exchange tube, a heat exchanger and an air conditioner, the heat exchange tube comprising a tube body (1), fins (2) being circumferentially provided on an outer wall of the tube body (1), a part of the circumferential region of each fin (2) being provided with protrusions, and the other part of the circumferential region of each fin (2) forming a smooth fin segment (6). By providing protrusions on the fins (2), such heat exchange tube can reduce the thickness of the liquid film adhered to the surface of the fins (2), so as to increase the heat exchange surface area, and this structure can enhance the local phase-change heat exchange capability thereof; meanwhile, the smooth fin segment (6) can reduce the liquid flow resistance and allow the liquid to flow out smoothly, preventing the liquid film from accumulating on the surface of the fins (2) which reduces the circumferential heat exchange area and increases the heat resistance, thereby comprehensively improving the overall heat exchange effect of the heat exchange tube.
